Connector bracket for a semitrailer of a semitrailer truck

Abstract

The invention relates, inter alia, to a connector bracket for a semitrailer of a semitrailer truck. Said connector bracket comprises a support element which can be swiveled about a bearing and a connector arranged inside the support element, the support element having a casing frame with a section that is complementary to an insertion opening of a fifth wheel. The aim of the invention is to provide a connector bracket or a plug-in coupling which is highly reliable even under adverse external conditions. This aim is achieved, inter alia, by the connector bracket according to the invention, wherein the casing frame can be displaced in relation to the connector by contact with the insertion opening, thereby displacing the connector from a closed standby position to an open coupling position.

1. A connector bracket for a semitrailer of a semitrailer truck, comprising: a support element which can swivel about a bearing and a connector arranged in the support element, the support element having a casing frame with a segment shaped complementary to an insertion opening of a fifth wheel, wherein the casing frame can move relative to the connector by making contact with the insertion opening and thus the connector can travel from a closed standby position to an opened coupling position. 
     
     
       2. The connector bracket according to  claim 1 , wherein the support element comprises a support frame, which engages with the bearing. 
     
     
       3. The connector bracket according to  claim 2 , wherein the connector is arranged on a closing plate, which is guided relative to the casing frame by means of a restricted guidance. 
     
     
       4. The connector bracket according to  claim 3 , wherein the restricted guidance is a link motion. 
     
     
       5. The connector bracket according to  claim 4 , wherein the link motion comprises two link walls formed stationary on the casing frame and guide cams of the closing plate engaging with the link walls. 
     
     
       6. The connector bracket according to  claim 5 , wherein the link walls are arranged on opposite sides of the casing frame. 
     
     
       7. The connector bracket according to  claim 5 , wherein the link wall is formed by two U-shaped links. 
     
     
       8. The connector bracket according to  claim 7 , wherein the links are arranged staggered in a horizontal direction next to each other. 
     
     
       9. The connector bracket according to  claim 7 , wherein the front U-shaped link has a front leg which broadens in a driving direction. 
     
     
       10. The connector bracket according to  claim 3 , wherein the support element has a lever plate, which is articulated by a first end to the support frame and by an opposite second end to the closing plate. 
     
     
       11. The connector bracket according to  claim 10 , wherein the lever plate or the support frame is configured with a shutter, which covers the connector when the casing frame is in the retracted position and no socket is present on a tractor vehicle. 
     
     
       12. The connector bracket according to  claim 10 , wherein at least one casing return spring is arranged between the support frame or the lever plate and the casing frame. 
     
     
       13. The connector bracket according to  claim 1 , wherein at least one guide rail is arranged in a lengthwise direction in the casing frame. 
     
     
       14. The connector bracket according to  claim 13 , wherein the at least one guide rail is led through the support frame. 
     
     
       15. The connector bracket according to  claim 3 , wherein at least one vertical spring is arranged between the support frame or the lever plate and the closing plate. 
     
     
       16. The connector bracket according to  claim 3 , wherein the closing plate is flexible in configuration and installed with pretension in the closed position.
